ROHM’s New 1200V IGBTs Achieve Industry-leading Low-loss Characteristics with High Short-circuit Tolerance

- Contributing to Higher Efficiency in Automotive Electric Compressors and Inverters for Industrial Equipment -

ROHM Co., Ltd. has developed fourth-generation 1200V IGBTs that are automotive-grade and qualified for AEC-Q101, combining class-leading* low-loss characteristics with high short-circuit resistance. This makes the devices ideal for vehicle electric compressors, high-voltage heaters, and industrial inverters. The current lineup includes four models in the RGA series in discrete packages (TO-247-4L and TO-247N), along with 11 bare chip variants with plans to further expand the lineup in the future.

In addition to these features, the devices achieve an industry-leading short-circuit withstand time of 10 microseconds (Tj=25 deg C), together with low switching and conduction losses while maintaining a high withstand voltage of 1200V and meeting automotive standards by reviewing the device structure, including the peripheral design.

Simultaneously, the new TO-247-4L package, which features four terminals, can accommodate an effective voltage of 1100V in a Pollution Degree 2* environment by ensuring adequate creepage distance between pins. This enables support for higher-voltage applications than conventional products.

*"Pollution Degree" indicates contamination levels in the surrounding environment. 2 refers to typical indoor environments.

Implementing creepage distance measures on the device side alleviates the design burden for manufacturers. Furthermore, the TO-247-4L package achieves high-speed switching by including a Kelvin emitter terminal, resulting in even lower losses. In fact, when comparing the efficiency of the new TO-247-4L packages with conventional and standard products in a three-phase inverter, the loss is reduced by approximately 24% compared to standard products and by 35% over conventional products -- contributing to higher efficiency in drive applications.

ROHM will continue to expand its lineup of high-performance IGBTs that contribute to greater miniaturization and higher drive efficiency in automotive and industrial equipment applications.
